A schwannoma is a soft tissue benign tumor that originates from Schwann cells of the peripheral nerve sheath. It is uncommon for it to occur in the foot. The tumor usually has an indolent presentation with a delayed diagnosis that may lead to irreversible nerve damage. The symptoms are related to the compression of the nerve due to the mass effect of the lesion. The authors report a case of a 62-year-old female with a history of breast cancer who was referred to the orthopedics department with pain in the dorsum of the right foot and a positive Tinel sign in the trajectory of the superficial peroneal nerve. The diagnosis of schwannoma of the superficial peroneal nerve was made, and the patient underwent surgery with complete resolution of symptoms. No deficits or recurrences were observed during the two-month follow-up period. The purpose of this report is to draw attention to the high index of suspicion and the need for a correct diagnosis for optimal clinical results.
施万细胞瘤是一种起源于周围神经鞘施万细胞的软组织良性肿瘤。它在足部较为罕见。该肿瘤通常表现为进展缓慢，诊断延迟，这可能导致不可逆的神经损伤。症状与病变的占位效应导致神经受压有关。作者报告了一例62岁有乳腺癌病史的女性患者，她因右足背疼痛和腓浅神经走行处Tinel征阳性被转诊至骨科。诊断为腓浅神经施万细胞瘤，患者接受手术治疗后症状完全缓解。在两个月的随访期内未观察到功能缺损或复发情况。本报告的目的是提醒注意高度的怀疑指数以及为获得最佳临床结果进行正确诊断的必要性。
